GPIO MPIN0 addressOffset = 0x2180

These registers are similar to the PIN registers, except that the value read is masked by ANDing with the inverted contents of the corresponding MASK register, and writing to one of these registers only affects output register bits that are enabled by zeros in the corresponding MASK register

Bit Symbol Description Reset value Access
17:0 MPORTP0 Masked port register (bit 0 = PIO0_0, bit 1 = PIO0_1, ..., bit 17 = PIO0_17). 0 = Read: pin is LOW and/or the corresponding bit in the MASK register is 1; write: clear output bit if the corresponding bit in the MASK register is 0. 1 = Read: pin is HIGH and the corresponding bit in the MASK register is 0; write: set output bit if the corresponding bit in the MASK register is 0. ext R/W
